RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 305,156, datedSeptember 16, 1884.

'7 Application filed December 21, 1823. (No model.)

To all whom it may concern:

Be it knownthat I, ARNOLD N. D. DELFFS,

of Bedford, in the county of Bedford and State of Tennessee, haveinvented a new and Improved Bailroad-Tie, ofjwhich the following is afull, clear, and exact description.

My invention relates to an improvement in railroad-ties, wherein I havebeton,wood, and iron combined and constructed into a tie, sub.-stantially as hereinafter set forth.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal section of a tie; Fig. 2, a cross-section ofFig. 1 on the linear m.

Fi 3 is a perspective view of the bed-piece;

Fig. 4, a perspective view of a wooden piece to be attached to the bed.

In my construction of an improved railroadtie I make the bed-piece A ofbeton concrete, formed in the usual manner. from gravel or broken stone,cement, and sand. These bedpieces, when molded, will have one or moreiron rods or wires, B, embedded in the material, extending throughthewhole length of the tie, to strengthen it. In each end of the bed isa mortise, C, having in the inner end a recess, D, to receive a woodenpiece, E, extending above the bed, to which the rail F will be securedby the spikes G. The bottom of the mortise, outside of the recess D, hasadowuward curve, L, extending across it, and the piece E has in the endfitted to lie over this curve a corresponding upward curve, H. The endpieces, E, of the tie are made of wood, to give to the tie a measure ofelasticity, and the curves G and H provide for an increase ofelasticity, as the rail F is secured to this wood piece directly overthese curves. The part I of the piece E, resting in the recess D, holdsthe said pieces in place and prevents therails from spreading. In thebottom of the recess D is a hole, K, through the bed A, to allow anywater that might get in said recess to es cape.

I may dispense with the curve H in the end erable with it.

of the bed-piece, as sufficient elasticity may be secured without it;but it will usually be pref- In this way, by combining concrete, iron,and wood, I make a tie at a moderate cost and well adapted to thepurpose.

. In building a new road the wooden blocks comprising the parts E and Imay be made in one piece, while in repairing the piece I has to beseparate and first placed in the recess D. The piece E is then put inplace and secured to it.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination of the concrete bed A,having one or more iron rods or bars, B, and the wooden pieces E,substantially as and for the purpose set forth.

2. The bed A, having the mortises G,in combination with the pieces E,substantially as and for the purpose set forth.

3. The bed A, having the mortises 0, curves L, and recesses D, incombination with the pieces E, substantially as and for the purpose setforth.

4. As a new article of manufacture, a rail road-tie constructed as setforth, and consisting of a concrete bed having metal rods or barsembedded longitudinally therein, and adapted to receive and retainwooden blocks for supporting the rails.

5. The railroad-tie having the bed A, provided with the mortises O,recesses D, and curves L, in combination with the pieces E, havingthepart I and curve H, substantially as and for the purpose set forth.

6. The bed A, having the mortises 0, re-

cesses D, and holes K, in combination with pieces E, substantially asand for the purpose set forth.

7 A concrete railroad-tie having metal rods or bars embeddedlongitudinally therein, substantially as and for the purpose specified.
